Time-reversal and PT symmetry breaking in non-Hermitian field theories
Thomas Suchanek, Klaus Kroy, Sarah A. M. Loos
We study time-reversal symmetry breaking in non-Hermitian fluctuating field theories with conserved dynamics, comprising the mesoscopic descriptions of a wide range of nonequilibri…

Irreversible mesoscale fluctuations herald the emergence of dynamical phases
Thomas Suchanek, Klaus Kroy, Sarah A. M. Loos
We study fluctuating field models with spontaneously emerging dynamical phases. We consider two typical transition scenarios associated with parity-time symmetry breaking: oscillat…
